Not that I've ever seen it, but based solely on the name of the picture file ("Ghoulies III - shower.plunger.jpg") I would guess Ghoulies III.

Yea, i was thinking maybe that could be it, but that couldve also been the name of the site that its originaly from, or the username of the person who originaly posted it, ect. I just wanted to be sure.

Not Ghoulies 4, that one didn't even have Ghoulies in it. So through process of elimination I'd say the picture file is correct. (Oh, just to warn you, I'd say that from what I've heard down the grapevine Ghoulies 3 isn't that cool)

It's certainly Ghoulies 3: Ghoulies Go To College. I have a VHS copy laying around somewhere, and I have no doubt about it being the film in question.

Neat fact about Ghoulies Three, the chick in that film Hope Marie Carlton, also played the role of Stiletto in the old PC game Noctropolis (not a bad game, BTW, although a bit frustrating at points.) I remember that solely because I thought she was pretty hot in that game and was curious to what else she might have done.
